Embodiment 1

[0015] as attached figure 1 As shown: the shock-absorbing and noise-reducing air hammer of the present invention includes a housing 1, the upper end of the housing is connected to the air intake cover 2, and the lower end is connected to the rear substrate 3, and an impact piston 4 is arranged inside the housing. The upper end of the impact piston absorbs the magnetic substrate 5 by electromagnetic force, the rear substrate has an exhaust hole 6 , and the outer end of the rear substrate has a rubber pad 7 . The setting of the rubber pad protects the wall of the equipment well, and at the same time effectively reduces the noise.

Embodiment 2

[0017] For the shock-absorbing and noise-reducing air hammer, a compression spring 8 is provided at the lower end of the impact piston.

[0018] work process:

[0019] When the air hammer is not fed with compressed air (3-7kg / cm2), the magnetic piston is tightly attached to the base plate at the rear end of the hammer body by strong magnetic force. When the solenoid valve is energized, compressed air flows into the air hammer body to increase the pressure in its body. When the pressure is greater than the magnetic force, the magnetic piston breaks away from the base plate at high speed, driving the hammer head on the piston to hit the front base plate of the hammer body at high speed, and the impact force is transmitted to the silo, knocking down the dust attached to the silo; when the solenoid valve stops energizing, the compressed air Exhaust, with the help of the return spring, the magnetic piston slowly rises close to the rear end substrate, and returns to the original s...

Abstract

The invention provides a damping and denoising air hammer. The conventional air hammer has the defects of high noise, high vibration and large damages to walls of equipment in a hammering process. The damping and denoising air hammer comprises a shell (1), wherein the upper end of the shell is connected with an air inlet cover (2); the lower end of the shell is connected with a back substrate (3); an impact piston (4) is arranged inside the shell; the upper end of the impact piston absorbs a magnetic substrate (5) through electromagnetic force; the back substrate is provided with an exhaust opening (6); and the outer end of the back substrate is provided with a rubber pad (7). The damping and denoising air hammer is taken as a forging machine.

Description

technical field [0001] The invention relates to an air hammer, in particular to a shock-absorbing and noise-reducing air hammer. Background technique [0002] Air hammer generally refers to the forging machine used in metal thermal processing. There are various specifications according to the forging capacity; the existing air hammer consists of a fuselage and a compressed cylinder installed inside, a working cylinder, a control valve, and The hammer head on the piston of the working cylinder and the anvil on the fuselage; the motor drives the compressed cylinder to work through the pulley, outputs compressed air, and controls the action of the working cylinder through the control valve. When the compressed air enters the lower part of the working cylinder when the valve is controlled, the piston drives the hammer. When the head is lifted and enters the upper part of the cylinder, the hammer head is pressed down; when in the forging position, the up and down movement of ...
